摘要
介绍一种柴油机气阀机构智能诊断仪 ,它基于TMS3 2 0C3 1和AT89C5 2双微处理器芯片。该仪器通过测量柴油机缸盖表面的振动信号 ,提取特征参数 ,对柴油机的气阀漏气与间隙异常进行诊断。此文同时给出了该诊断仪系统的软硬件设计原理。
The development of DSP has greatly prmonted high precision and intelligent industry instrument. This paper introduces a kind of diesel valve diagnosis instrument based on dual MCU of TMS320C31 and AT89C52. The instrument measures vibration signal of diesel cylinder header, extracts the characteristic parameters, to diagnosis for fault of leakage and abnormal space of valve. This paper deals with the design principle of software and hardware in this instrument.
